JavaScript date.toJSON() method converts the given date object’s contents into a string. The date object is created using the date() constructor.
Syntax:
dateObj.toJSON()
Parameters: This method does not accept any parameter. It is just used along with a Date object created using the Date() constructor.
Return Value: It returns the converted string of Date() constructor contents.
Note: The DateObj is a valid Date object created using the Date() constructor whose contents are converted into a string.
Below are examples of Date toJSON() Method:
Example 1:
javascript
// Here a date has been assigned// while creating Date objectlet dateobj =Â Â Â Â new Date('October 15, 1996 05:35:32');Â
// Contents of above date object is converted// into a string using toJSON() method.let B = dateobj.toJSON();Â
// Printing the converted string.console.log(B); |
Output:
1996-10-15T00:05:32.000Z
Example 2: Here nothing as a parameter is passed while creating a date object but still toJSON() method returns the current day name, month name, date, year, and time.
javascript
// Here nothing has been assigned// while creating Date objectlet dateobj = new Date();Â
// Contents of above date object is// converted into a string using toJSON() method.let B = dateobj.toJSON();Â
// Printing the converted string.console.log(B); |
Output:
2018-04-23T11:24:14.955Z
Example 3: When some random list of values is passed, then the toJSON() method returns the corresponding produced string. The format for the Date() constructor is like Date(month, date, year, time). By following this format some values is given in the below program and the corresponding string is produced as output. The time format should be like (number:number: number).
javascript
// Here some different values has been// assigned while creating Date objectlet dateobj1 = new Date('1');let dateobj2 = new Date('2, 3');let dateobj3 = new Date('4, 5, 6');let dateobj4 = new Date('4, 5, 6, 11:00:12');let dateobj5 = new Date('12, 5, 4, 0:0');Â
// Contents of above date objects is converted// into strings using toJSON() method.let B = dateobj1.toJSON();let C = dateobj2.toJSON();let D = dateobj3.toJSON();let E = dateobj4.toJSON();let F = dateobj5.toJSON();Â
// Printing the converted string.console.log(B);console.log(C);console.log(D);console.log(E);console.log(F); |
Output:
2000-12-31T18:30:00.000Z 2001-02-02T18:30:00.000Z 2006-04-04T18:30:00.000Z 2006-04-05T05:30:12.000Z 2004-12-04T18:30:00.000Z
Note: Months, Dates, hours, minutes, seconds, and milliseconds must be in their respective range of 0 to 11 for months, 1 to 31 for dates, 0 to 23 for hours, 0 to 59 for minutes, 0 to 59 seconds, 0 to 999 for milliseconds otherwise toJSON() method return null.
Example 4: Here date is given as of 45 which is out of range of the date that is why the below code gives the output as null.
javascript
// Here a date has been assigned// while creating a Date objectlet dateobj =Â Â Â Â new Date('October 45, 1996 05:35:32');Â
// Contents of above date object is converted// into a string using toJSON() method.let B = dateobj.toJSON();Â
// Printing the converted string.console.log(B); |
